Re: PATCH: anonymous functions in PHP

I didn't make it do anything fancy with scoping; it would make the implementation more complicated, and wouldn't fit so well with the way that scoping works in PHP, in that you need to explicitly reference the global scope to "break out" of your function scope. It would be cool if the lexical scope was inherited, but maybe not cool enough to warrant making it work :) --Wez. On Mar 18, 2007, at 10:06 PM, Stanislav Malyshev wrote:

What happens if you do this: $data = array("zoo", "orange", "car", "lemon", "apple"); $rev = 1; usort($data, function($a, $b) { return $rev?strcmp($a, $b):!strcmp($a, $b); }); var_dump($data); # data is sorted alphabetically This works in Javascript (probably Ruby too), but quite hard to make work in PHP because $rev is in different scope. Moreover, would it mean that this: $f = function($a, $b) { return $rev?strcmp($a, $b):!strcmp($a, $b); } would work too? Keeping right value of $rev? --Stanislav Malyshev, Zend Products Engineer stas@zend.com http://www.zend.com/
